After reading several post about the Viva Nova I noticed one person actually noticed a small tube in mouth piece that extends down with a little silicone seal on it and talked about pushing it down. I wish I could find the post to give my thanks for bring this to my attention. Now I have been experiencing some flooding before I pushed this tube down with a q tip. Only time will tell and I will update this post if it does help. I use 100% PG so I thought it was just the juice that was causing it. Am I the only one that didn't know about that little tube? Mine was all the way up in the mouthpiece so I hope this helps.
Well David, all I can say is you have given me a great big happy. Yes I saw that tube about halfway up inside the stock vvn mouthpiece. I even pushed it out, examined it and pondered on why was it so long. I thought it was like a little silicone ring to catch condensated vapor from reaching my lips as Kemosabe said. But after further investigation, why is it so long? It's probably 5mm and why the slight bevel on the bottom end?
I'm convinced you (and the other poster) have hit the nail on the head. That little tube should be extending out of the bottom of the stock tip about 3mm before you stick the tip in, It'll then barely protrude throught the hole in the top cap and form a slight seal against the silicone ring/cap on top of the head which holds the coil. It forms a channel right up into the tip and it has reduced the condensation in the recessed area of my top cap by a good 80-90%. So far no more slight taste of juice in my mouth and no more having to pull the tip on a regular basis to wipe out all that condensation. It also prevents backwash back into the coil and tube area apparently.
I like to use my ming tip on the vvn so later I plan to do some length comparisons and if it'll still reach far enough to make the seal I'm going to take a small needle file and open up the bottom hole on my ming tip just a hair bigger so I can push that silicone tube up into it about 2mm. Your method of pushing it down through the stock mouthpiece with a q-tip works very well... just push all the way down in there until you hit slight resistance. If you push just a bit harder, it'll actually stay down in the topcap when you pull the mouthpiece out and you can look down in there at it and tell exactly what it's purpose is. Quite clever actually.
Ty mate, I think you have solved my biggest gripe against my vvn tanks.
) and then screw on the top of my vivi nova. No more flooding, for me at least. I tried all three heads and had problems flooding with all of them till I started doing this. I only have one vivi nova and am still on the fence about its performance.
